Question
(2) Of the 6 Enzyme Commission classifications of enzymes, what is the first of the four numbers (1-6) for amino acid racemase? (3) Enzyme kinetics are determined under initial rate conditions, wherein the initial substrate concentrations changes very little, because: (A) (B) (C) Products do not accumulate and inhibit the forward reaction Enzymes are unstable under most assay conditions, and rapidly lose activity The substrate concentration does not change appreciably and so does not create an additional variable (D) All of the above (E) Some of the above (4) The initial velocity data of an enzyme that utilizes two substrates, A and B, displays parallel lines when plotted as 1/v vs. 1/[A] and changing-fixed concentrations of B and also for 1/v vs. 1/[B] for changing-fixed concentrations of Substrate A. The catalytic mechanism of this enzyme probably involves (A) The action of a coenzyme (B) Uncompetitive inhibition (C) A covalent enzyme-substrate intermediate (D) The release of a product before completion of catalysis (E) More than one of the above (5) Three enzymes have substrates with the kinetic parameters in the table below Which enzyme is under diffusion-control? (circle the correct enzyme, please) keat (s1) 10000 20 100 Km (HM) 2000 Enzyme 0.1Explanation / Answer
Answer for question number 2 : The first four enzyme commission number for amino acid racemases is 5.1.1.10.
These enzymes catalyses the interconverssion and L and D amino acids.
